The ASC Engineered Solutions 2X1B.BMC is a black malleable iron pipe reducing coupling rated at 150 lb, designed to connect pipes of two different diameters in threaded piping systems. With a 2-inch by 1.25-inch nominal size and female NPT (FNPT) ends on both sides, it provides a secure, pressure-rated transition between pipe runs. Malleable iron construction offers the toughness and ductility needed for mechanical and gas distribution piping. This fitting is domestically manufactured and carries a standard black finish suitable for use in gas, air, and general-purpose piping applications. It is installed by licensed plumbers, pipefitters, and mechanical contractors.
This reducing coupling is suited for residential and commercial piping systems where a diameter reduction is required within a threaded black iron pipe assembly. Common applications include natural gas supply lines, compressed air distribution, and steam or water piping at low-to-medium pressure. The FNPT thread pattern on both ends accepts standard NPT-threaded pipe, making it straightforward to integrate into new construction or retrofit installations.
Designed as an OEM-style replacement or new-installation fitting for standard 150 lb threaded black iron pipe systems using NPT connections.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable codes such as the IFGC or IPC. Shut off and depressurize the piping system completely before making or breaking any threaded connections. Apply an appropriate thread sealant or PTFE tape to the male NPT threads before assembly, and tighten to the fitting manufacturer's standard engagement depth without over-torquing. Inspect all joints for leaks after restoring system pressure.
